DS90C032BTMX - 155.5 Mbps LVDS Receiver | Texas Instruments
MPN: DS90C032BTMX ✓ AktifDS90C032BTMX Genel Bakış
An LVDS receiver is a differential line receiver within the broader interface IC and semiconductor hierarchy. Low Voltage Differential Signaling transfers data across two conductors whose voltage difference carries the signal. This differential approach supports high-speed communication while allowing the receiver to reject common-mode noise that can affect single-ended links. The DS90C032 integrates four differential receiver channels and converts LVDS inputs to CMOS-compatible outputs.
The device's principal characteristics include four receiver channels, LVDS signaling, CMOS output logic, and operation above 155.5 Mbps. Its four-channel architecture reduces the number of receiver packages required in systems transporting several parallel differential signals. The 16-pin SOIC package is a conventional surface-mount gull-wing package suitable for high-density point-to-point and backplane interfaces.
Technical operation depends on the differential input network, receiver threshold behavior, output timing, and the power rails shown in the manufacturer datasheet. Because the supported data rate is specified in excess of 155.5 Mbps, PCB signal integrity becomes important at the upper operating limit. Differential impedance, pair symmetry, connector geometry, return paths, and receiver placement can affect signal integrity and must be evaluated as a complete channel.
Typical applications include parallel LVDS links between circuit boards, high-speed backplane interfaces, industrial data acquisition systems, video transport links, and communications equipment using the companion DS90C031 or DS90C031B line driver. The DS90C032 is particularly appropriate where four channels and low-power differential reception are required within a compact package.
Design the board with continuous differential routing, matched impedance, short return paths, and carefully controlled connector transitions. Decoupling should be placed close to the device supply pins, and unused inputs should be handled according to the logic levels and input-state requirements in the manufacturer datasheet. Signal-integrity simulation or measurement is recommended when the link operates near 155.5 Mbps.

High-Speed Board-to-Board Links
The DS90C032BTMX fits parallel board-to-board links that require four low-power LVDS receiver channels and data rates above 155.5 Mbps. Its four integrated differential receivers convert the LVDS input pairs to CMOS-compatible outputs, reducing the number of separate receiver packages on a communication card. Pair each differential route with matched impedance, preserve symmetry between the conductors, and minimize stubs and layer transitions. The 16-pin SOIC package also supports standard gull-wing assembly. Because operation near the upper rate is sensitive to reflections and loss, engineers should measure the complete transmitter-to-receiver channel rather than relying only on device specifications.
Önerilen
Industrial Backplane Interfaces
The DS90C032BTMX is appropriate for industrial backplane modules that exchange several low-voltage differential signals across a multi-board chassis. Four receive channels in one 16-pin SOIC device provide a compact receiver arrangement, while the greater-than-155.5-Mbps capability supports high-speed point-to-point traffic. Industrial designs should preserve a continuous ground reference beneath each differential pair, control connector and via impedance, and keep the receiver away from unrelated high-current switching paths. Review the complete differential insertion-loss and jitter budget at the intended operating rate. The receiver's industrial temperature grade also makes it a better starting point than a consumer-grade option when environmental qualification is required.

Video Transport Systems
The DS90C032BTMX can receive low-voltage differential signals in multi-channel video transport equipment when the system uses a compatible CMOS-based link architecture. Its four LVDS inputs allow several related channels to be received through one package, and the device supports rates above 155.5 Mbps for high-speed point-to-point transfer. The receiver does not itself perform video formatting, so upstream circuitry must generate valid differential data and downstream logic must handle the recovered CMOS outputs. Maintain equal routing lengths within each pair, provide a nearby low-inductance ground path, and verify connector transitions with channel measurements. These practices reduce timing uncertainty in a multi-channel video transport system.

High-Speed Data Acquisition
The DS90C032BTMX is suitable for data-acquisition and test systems that receive low-power differential signals from remote sensing or processing modules. Its four channels support parallel acquisition links, while the greater-than-155.5-Mbps data-rate capability enables fast transfer from source devices to a controller. Place the receiver near the connector or cable transition when possible to minimize trace loss, and route each differential pair over a continuous reference plane. Input protection must be selected so that it does not degrade the LVDS receiver's input behavior or introduce excessive capacitance. The 16-pin SOIC footprint is compact enough for acquisition modules that need multiple links without consuming excessive board area.

Point-to-Point Communications Equipment
The DS90C032BTMX supports communications equipment requiring a compact, low-power receiver for high-speed differential links. The Texas Instruments device combines four LVDS channels with CMOS outputs in a 16-pin SOIC package, allowing it to sit near a connector and feed recovered data into a system controller. The companion DS90C031B line driver can establish the transmit side of the link. Keep power and ground connections short, place bypass capacitance close to the receiver, and avoid routing differential signals across split planes. At the upper supported rate, evaluate source rise time, cable loss, receiver threshold margin, and jitter together. This channel-level review is essential because individual component specifications cannot guarantee interface performance.
Önerilen
Parallel Digital Backplanes
The DS90C032BTMX can be used as the receive element of a parallel digital backplane carrying several low-voltage differential signals. Its four-channel organization limits package count compared with discrete single-channel receivers, and its 16-pin SOIC package simplifies assembly in conventional PCB technology. The design must maintain consistent differential impedance from source to destination and use connector pin assignments that preserve pair symmetry. Stitching planes, high-speed switch fanout, and changes in reference layers can create discontinuities that are not visible in a schematic. Engineers should therefore characterize the assembled backplane with time-domain or equivalent channel measurements, particularly when operating above 77.7 MHz where timing and jitter margins become more restrictive.

Tasarım Notları
Route each LVDS input pair as a tightly coupled differential pair over a continuous reference plane. Maintain equal impedance and consistent pair spacing through vias, connectors, and layer transitions. Avoid adding test pads or stubs unless their loading has been included in signal-integrity analysis. The receiver's greater-than-155.5-Mbps capability leaves little tolerance for uncontrolled reflections, so channel measurements should be performed on representative hardware.
Do not substitute the receiver for an LVDS line driver or connect differential data to a single-ended interface without an appropriate converter. The DS90C032BTMX receives differential LVDS inputs and produces CMOS outputs. Verify the enable state, output logic, supply requirements, and unused-input handling against the manufacturer datasheet before power-up. A footprint match alone does not establish electrical compatibility.
Place the receiver close to the cable or connector entry point when possible to reduce trace loss and improve timing margin. Provide a low-inductance ground return and place the device's bypass capacitance at the supply and ground pins according to the datasheet reference layout. Keep unrelated switching nodes and high-current paths away from the differential inputs and CMOS outputs to limit coupling into the recovery threshold.
